One of the most common problems with burning a Linux install CD/DVD is that people sometimes don't understand that an iso image file is not a normal file. You cannot just burn the iso to disc to and expect it to work. I repeat: '''you cannot simply put the iso file on a blank disk and expect it to work'''. In order to properly make a CD or DVD out of an iso image, you need special software. Instructions for Nero and Isorecorder are included; for other programs, see the manual for the software, or just give one of these a shot.

For checking the integrity of the burned disc, please see:

With Nero you just select file and burn image, then select the .iso file you want to burn. The software handles the rest.

If you're looking for a good, alternative freeware solution, you can download a free image burner.

Many people know they can check if a downloaded ISO file is OK by comparing the md5sum of the ISO file against the md5sum posted on the SL mirrors. For example:

+

+

{{Console| <pre class="clear">

+

# md5sum -c SabayonLinux-x86_64-3.4f.iso.md5

+

SabayonLinux-x86_64-3.4f.iso: OK

+

</pre>}}

+

+

cf. the contents of ftp://bo.mirror.garr.it/mirrors/sabayonlinux/SabayonLinux-x86_64-3.4f.iso.md5 which are:

+

645600788920443b372baae3544acffa SabayonLinux-x86_64-3.4f.iso

+

+

so the ISO I downloaded was good.

+

+

Remember - verify the MD5 sum for the version of Sabayon that you downloaded - they are all different. The MD5s can be found on the mirrors listed at: http://www.sabayonlinux.org/mirrors

+

+

But a different method is needed to verify the integrity of the LiveDVD/CD itself. You should select the verify written data checkbox in K3b before burning the DVD/CD, but if you forgot or still have doubts then the following methods can be used to check the integrity of the burnt LiveDVD/CD:

+

+

'''EDIT (May 24, 2012): Method 1 and Method 2 below for Linux no longer work, so jump to the end of this article for the latest method to use if you are not using Windows. If you are using Windows, see Method 3.'''

+

+

+

+

'''Method 1'''

+

+

If you know the md5sum from the mirrors, you can find the md5sum of the LiveDVD/CD you burnt and compare the two.

+

+

a) Boot up SL as usual from the HDD, then put the LiveDVD/CD in the optical drive.

Notice that the value I have used for bs= in the second command is the "Logical block size" displayed from the first command, and the value I have used for count= in the second command is the "Volume size" displayed from the first command. Make sure you use the values returned when ''you'' run the first command.

+

+

The long alphanumeric string displayed should equal the m5dsum published on the SL mirrors provided that you recorded the LiveDVD/CD using 'session at once' mode (single session, disk-at-once), not 'track at once' mode (multi-session, track-at-once).

+

+

In this example (SL x86-64 3.4f), the md5sum published on the mirrors for the ISO file is:

+

645600788920443b372baae3544acffa SabayonLinux-x86_64-3.4f.iso

+

+

Notice that this matches the md5sum of /dev/cdrom as displayed by the second command above, so the burn was good. If it does not match the md5sum published on the mirrors then the LiveDVD/CD is useless and you need to burn another one.

+

+

+

'''Method 2'''

+

+

If you know the ISO you downloaded from the mirrors is good (because you checked the md5sum), you can create an ISO from the LiveDVD/CD and compare it with the good ISO.

+

+

(In the example below I assume the original ISO you downloaded is on your desktop, so alter the path accordingly if it is somewhere else on your PC.)

+

+

a) Boot up SL as usual from the HDD, then put the LiveDVD/CD in the optical drive.

Notice that the value I have used for bs= in the third command is the "Logical block size" displayed from the first command, and the value I have used for count= in the third command is the "Volume size" displayed from the first command. Make sure you use the values returned when ''you'' run the first command.

+

+

If the result of the diff (compare file) command is just the usual prompt then the files are identical and the burn was good. In the example above it was. But if the result is:

1. I have not checked if the method for Windows on the above-mentioned Web page actually works, so use it at your own risk.

+

+

2. The method for checking the integrity of a LiveCD under Linux, given on the Web page mentioned under Method 3, does not work for me. If I use the command '''md5sum /dev/cdrom''' it does '''not''' return the same md5sum as published on the mirrors '''even though the LiveCD is good'''. So do not use that method under Linux, use either Method 1 or Method 2 given in this Wiki article.

+

+

+

----

+

+

EDIT (May 24, 2012): Method 1 and Method 2 no longer work, and the method for checking the integrity of a LiveCD under Linux, given on the Web page mentioned under Method 3, does now work. This is how to do it:

+

+

Insert the LiveDVD into the optical drive, let the disc spin up and then enter the following three commands:

+

+

{{Console| <pre class="clear">

+

md5sum /dev/cdrom | awk '{print $1}' > md5a.txt

+

md5sum ~/Sabayon_Linux_8_amd64_K.iso | awk '{print $1}' > md5b.txt

+

diff -qs md5a.txt md5b.txt

+

</pre>}}

+

+

(Obviously change the path and/or the ISO file name to match your circumstances.)

+

+

If you get an error message while the md5sum is reading the disc, there must be something wrong either with the burn or with the optical drive itself.

+

+

If you get the message "Files md5a.txt and md5b.txt differ" then the burn was bad.

+

+

If you get the message "Files md5a.txt and md5b.txt are identical" then the burn was good.

Visual walkthrough Booting process

When having a old NVidia card, and downloaded latest ISOs, chances are that they will not start the Window Manager/Desktop Environment (see the flavors above), but rather present you with a black screen.

There is nothing wrong with the ISOs, it is because "nvidia-drivers-304.64" or higher is installed by default.

You can bypass that by hitting ctrl-alt-f1, remove the nvidia-drivers, (nouveau is installed too) and restart xdm:
